Navigation commands
There are several commands that are useful in moving from one part of the menu tree to another. The commands are similar to those used in a UNIX® shell:
cd | This command moves you to a given spot in the menu tree. Entering |
| cd / always takes you back to the main menu. |
pwd | This command displays the current menu path where you are in the |
| menu tree. |
up | This takes you back to the last menu that you touched. |
.. or cd .. | Both of these commands take you up one level in the menu tree. |
pushd and popd | These commands allow you to manage a stack of menus that you visit |
| frequently. |
history | This command displays the last several commands that you entered. |
| You can reuse these commands by typing an exclamation point (!) |
| followed by the number of the command as displayed. |
quit or exit | Both of these commands terminates your session. |
Configuration control commands
These commands control the effectiveness of changes to the switch configuration. The general rubric for configuring the switch is EASY:
E for editing the configuration, typing in your changes
A for the apply command which makes the changes part of the running configuration
S for the save command which writes the changed configuration to flash memory
Y for yes, which is the answer to the prompt to be sure that you really want to update flash
Additional configuration control commands include the following:
diff | This command displays the differences between the most recent edits |
| and the running configuration. |
diff flash | This command displays the differences between the running |
| configuration and its flash copy. |
revert | This command discards all changes which have not yet been applied. |
revert apply | This command discards applied changes which have not yet been |
| saved to flash. |
Additional commands
These are additional commands that facilitate troubleshooting or are otherwise helpful:
ping | Sends ping, Internet Control Message Protocol (ICMP) echo, requests |
| to the specified IP address. |
traceroute | Traces the IP path to a specified IP address. |
who | This command shows who is logged on to the switch and from which |
| address. |
telnet | Opens a Telnet session to the designated IP address. |
verbose | Tailors the level of messages displayed on your session. |
lines | Controls the number of lines per screen for display purposes. |
